I read the instructions for this product before installing it and it worked great. I had several window panes coming off the sides and I contacted the seller about this. They responded in just a few hours with some advice that was helpful and solved my problems. It's best not to remove all of the protective film at once, but to remove it slowly by pressing with a straight edge. I also mounted this to a window that has a vent directly below it and I think that gave me trouble as well. So if air is blowing directly on the window, it's best to close it if you close the vent or close it if you can. After a few days, the foil does not come off. It lets in a lot of light but the view through it is distorted, giving you privacy but still allowing natural light to enter the room.
